Adjustable Magazine Head for Handgun Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handgun magazines often face dimensional deviations in breech block housings due to different models and construction years, leading to interference with the ejection of cartridge cases, particularly with the ejector and extractor mechanism.
Innovation Solution
A magazine design with an adjustable magazine head and ejector plate that can be positioned relative to the breech block housing, allowing for adjustment via screws and a swiveling mechanism to accommodate various firearm models and years, ensuring proper ejection functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed magazine head design is used, then the manufacturing is simple, but the magazine cannot accommodate dimensional deviations in different firearm models and construction years
Solution Approach 1:
The magazine head is designed with adjustability, allowing it to change position relative to the magazine body through a locking mechanism. This dynamic capability enables the magazine head to adapt to dimensional variations in different firearm models and construction years, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The magazine is divided into separable components: the magazine body and the magazine head can be independently adjusted and locked at different positions. This segmentation allows the magazine head to be positioned separately to accommodate various firearm dimensions without redesigning the entire magazine structure.
2Reliability
If the magazine head is made adjustable to fit different models, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The adjustment mechanism includes a locking system that secures the magazine head at the desired position without requiring additional tools or complex operations. The user can independently adjust and lock the magazine head, ensuring reliable ejection function while minimizing the complexity of the adjustment mechanism.
3Reliability
If a precise fit is required for the magazine head in the breech block housing, then the ejection function is reliable, but manufacturing precision requirements increase
Solution Approach 1:
Instead of requiring high manufacturing precision for a fixed fit, the magazine head is designed to be adjustable and lockable at different positions. This dynamic adjustment capability compensates for dimensional deviations in the breech block housing across different firearm models and construction years, ensuring reliable ejection function without stringent manufacturing precision requirements.

AI summary
The invention relates to a magazine for a handgun, comprising a chamber that accommodates the ammunition and a magazine head that is suitable for being accommodated by the magazine shaft in the breechblock housing of the gun, characterized in that according to the invention an ejector plate is arranged on the magazine head and means are provided for changing the relative position of said ejector plate in the magazine shaft when a magazine is inserted. The solution according to the invention makes it possible to change the position of the magazine head in the magazine shaft by means of an adjusting mechanism and thus to also change the relative position of the ejector plate, which is now on the magazine head, in the magazine shaft. In the process, the position of the ejector plate relative to the feeding web of the breechblock generally changes. By adjusting the position of the magazine head, the ejection angle and/or the ejection path of the cartridge case and the position of the fed cartridge relative to the cartridge chamber of the weapon can also be changed if applicable.
